Penn State running back Zach Zwinak suffered a wrist injury during the Blue-White Game that will keep him out of contact drills until the middle of training camp, coach Bill O'Brien said Tuesday.

"I don't want to get into the details on what he did, but he should be ready to go for training camp," O'Brien said at the Penn State Coaches Caravan stop at Berks Campus. "It'll probably be a non-contact situation (for the first half of camp). It's not life-threatening. He'll be ready to go in the middle of training camp."

Zwinak enjoyed a breakout season last year, rushing for 1,000 yards and six touchdowns. Bill Belton and Akeel Lynch are behind Zwinak on the depth chart. His injury has left O'Brien considering changes to the Blue-White Game for next year.

"I think the Blue-White Game is fantastic for our fans," O'Brien said. "But I think we're going to have to make some decisions, especially in the era that we're in now (with Penn State's scholarship limitations). You can't get your best players hurt in the spring game."

•McGloin in camp: Former Penn State quarterback Matt McGloin said Tuesday that he will attend rookie camp with the Washington Redskins Thursday with hopes to earn a free agent contract and a roster spot for training camp.

"It was a difficult process," McGloin told the Scranton Times-Tribune. "We waited for offers to come in, and we had six to eight teams contact us. I decided to go to Washington, where I think I can make an impact. Hopefully I will prove that I can get the job done and impress some people."

Mark Magazu II, McGloin's agent, said in a statement that if his client is not offered a contract after the Redskins minicamp he would attend a camp next weekend with another team.

Magazu said that McGloin was offered a contract from an undisclosed team after the NFL draft, but he "respectfully declined."

McGloin passed for a school-record 3,266 yards last season and tied school records for touchdown passes in a season (24) and a career (43). He finished as the second-leading passer in Penn State history with 6,385 yards.

•Stanko leaves team: Redshirt freshman Anthony Stanko, who was part of Bill O'Brien's first recruiting class, has decided to leave the team, O'Brien said.

Stanko, a guard who did not play last season, will stay enrolled at Penn State and will remain on scholarship, which is allowed under the NCAA sanctions imposed last year.

Offensive tackle Luke Graham and linebacker Dakota Royer left the team last year and also stayed enrolled at Penn State and on scholarship. Royer was scheduled to graduate this week.

The scholarships of Stanko and Graham count against Penn State's total number, which has to be down to 65 for next season.

"We'll probably play this season with 64 scholarship players," O'Brien said.

•Caravan nuggets: Penn State football coach Bill O'Brien and men's basketball coach Patrick Chambers participated in a question-and-answer session during their appearance at the Coaches Caravan stop at Berks Campus.

O'Brien was asked about whether he plans to change Penn State's basic and distinctive uniforms. Last year he put the names of the players on the back of the jerseys to recognize them for sticking with the team and the school.

"We'll never have the array of uniforms that the Oregon Ducks have," O'Brien said. "You have to come to the games (to find out if there will be changes to the uniforms and helmets). Then you'll find out."

O'Brien said Penn State continues to work on scheduling a game in Ireland in 2014 or 2015.

"There's a very good chance," he said, when asked about the Lions playing across the Atlantic Ocean.
